Drywall Finish Levels
From Open Source Ecology
Basics
- In Architecture and Construction Drywall is Classified on a Scale from 1-5 Based on what Finishing Steps are Taken
- Useful for design planning, but also when subcontractors as there is a standard to be done, and thus no "who done it" between Painters and Drywallers if they are different companies
Unknowns
- 1.) Seems there may be disagreement on the exact levels?
- Need to see if there is an official standard written somewhere, or if the slight variation is acceptable in typical literature (and just...contractors talking lol)
- 2.) Code Requirements/Definitions
- 3.) Industry Standards / Customer Preference / Value vs Labor Spent (This also ties into ergonomics/Manufacturing Engineering of it all planning)
- 4.) How they play into Architecture
- Supposedly Level 5 is only required in very bright areas/areas with "harsh lighting"
- Also certain paints; Drywall Shorty's Video Mentioned use for High Gloss Paints to prevent "Flashing"
- Early Morning Sun and Sunset Light
- Then derive a sort of protocol (or maybe even Plugin for MSH3D / Blender !) for choosing when to use what
- This ties into Architectural Lighting Simulation (Heard about this on a jobsite recently, you use the file to say where the lights will be and what model they are etc, it does the simulation and shows a "heat map" of sorts. Allows for not just aesthetic planning without Trial and Error but also prevents Overlighting )
Levels
Level 0
Level 1
- Drywall Tape Is Applied to the Joints Between Sections of Drywall
- Joint Compound is applied only over the tape and Drywall Screw Tops (Also it does not need to be done cleanly (if higher levels are not being done afterwards) as it's main goal is attaching the tape and making a seal, not aesthetics)
- It is sometimes caused "Firetaping" as it is Required for Building Code in some areas (Grabbing a Citation + What Local Areas Require, if it isn't a nationwide thing, is a good idea for here), even if the people paying for the work may have wanted a Level 0
Level 2
Level 3
- A Second Coat (And more "Proper" looking ie not Translucent) is Applied Above a Level 2 Finish
Level 4
- A Third Coat is Applied and Drywall Sanding
- This can also be thought of as the second "proper" one, akin to only 2 layers of paint...which are over one layer of primer
Level 5

- Drywall
- Surface Prep
- Drywall Installation Process
- Surfacer
- An Alternative to a Proper Level 5 Finish, Similar Purpose but more Paint-Like, Vancouver Carpenter Mentioned it (as well as anecdotal evidence of it messing the drywall up, need to dig into this
- Also (outside of potentially cost) using the same Drywall Mud reduces products needed which can be of use

- An Article by The Spruce Titled "Drywall Finish Levels Explained" (Great Infographic, need to check licensing on it)
- A Video by the YouTube Channel "Erin Stetzer Homes" Titled "The Difference Between Level 4 and Level 5 Sheetrock Finishes" ( ~2 Minute Watch )
- Alright, but a bit surface level, also various aspects (Lack of any dirt on them / not wearing steel toes or work clothes etc, and calling the screws nails (maybe just a slip up though) make me doubt their true expertise, granted it is a decent short primer (bit of a pun there) on it all
- A Video by the YouTube Channel "Drywall Shorty" Titled "Drywall finishing levels explained" ( ~5 Minute Watch )
- This lady DEFINETLY knows her stuff, between way talking about stuff then also on the about page quote "Hi, I'm Lydia aka Drywall Shorty! I am a drywall finisher in Montana with over 20 years experience. I am a weekly contributor to Build Show Network, taught a comprehensive course on finishing" so major SME points on that
- Used some terms i'm unfamiliar with, mainly on the taping bit (said joints, butts, and flats. I need to read up how those differ) (Also "Corner Beads" and "Boxed" )
- She said that Level 3 is the highest you go if you are using Wall Texturing / Ceiling Texturing
- Considered Level 3 Two Coats, Level 4 is Considered "Smooth Wall" (No Drywall Tool Marks )
- A Video by the YouTube Channel "Vancouver Carpenter" Titled "What does Level 5 Drywall mean?" ( ~8 Minute Watch )
- Describes something along the lines of a 4.5 Level Finish around timecode 3:04
- Does a "hands on" demo, rather than just a walkaround with a single piece of drywall as a model of sorts (At Timecode 3:37)
- Different "Sections" Before it was painted were:
- "Unsanded Paper" (Basically raw drywall) Between Stripes of Mud (and Maybe Tape) to Simulate the Patterns Created by Seam Taping and Screw Head Mudding
- Level 4 Sanded Drywall Mud
- A Video by the YouTube Channel "Vancouver Carpenter" Titled "EXTREME LEVEL 5 DRYWALL!!!" ( ~27 Minute Watch )
- A Full Step by Step Walkthrough of Doing a Level 5 Finish for a Ceiling
- Interesting bit at timecode 9:34
- Mentions how the upper corner/lip will be difficult to sand, either with Sandpaper or with a Sanding Block
- Intrigued me from a Design for Construction / Ergonomics aspect, something i've really been thinking over, either way even if there is some "trick" to still do it but do some more efficiently, may be worth a look
